Overview
Hachi's 砂の惑星 feat. HATSUNE MIKU, officially titled "DUNE" in its English release, is a Vocaloid track that entered the maimai song library as part of the MiLK version update in December 2017. Classified under the niconico & Vocaloid genre within the game, the song pairs Hachi's signature electronic production with Hatsune Miku's synthesized vocals over a deliberate, mid-tempo groove at 95 BPM, a relatively unhurried pace compared to many of the high-energy tracks in maimai's Vocaloid catalog.
The maimai charts span four difficulties, with the Expert chart designed by Jack and the Master chart (level 13) designed by はっぴー (Happy). Over the course of its tenure in the game, 砂の惑星 has undergone one of the more extensive level-revision histories in the maimai library. The Basic chart was reduced from level 4 to level 2, Advanced rose from 6 to 7, Expert climbed from 9 to 10+, and Master increased from 12 to 13 across successive version transitions, reflecting how maimai's difficulty calibration has tightened with each major update. The difficulty constants for all charts were documented by the community survey group CiRCLE.
